A gum infection can often be resolved with a combination of professional dental treatment and consistent home care. Mild infections may start healing within a week, while moderate cases typically take two to three weeks, and severe infections requiring surgery can take months. The right approach depends on how far the infection has progressed.
Recognizing What You’re Dealing With
Gum infections range from gingivitis, which is inflammation limited to the surface of your gums, to periodontitis, where bacteria have worked their way below the gumline and started damaging the bone that holds your teeth in place. Gingivitis shows up as red, swollen gums that bleed when you brush. Periodontitis adds deeper symptoms: persistent bad breath, gums pulling away from your teeth, loose teeth, or pus between the gums and teeth.
A dental abscess is the most serious form. This is a pocket of pus caused by a bacterial infection, and it can spread quickly. If you’re having difficulty breathing, swallowing, or opening your mouth, or if you notice swelling around your eye or significant swelling inside your mouth, that’s a medical emergency requiring immediate care.
What You Can Do at Home Right Now
Home care won’t cure an established gum infection on its own, but it can reduce inflammation, manage discomfort, and support healing alongside professional treatment.
Saltwater rinses are the simplest starting point. Mix one teaspoon of salt into eight ounces of warm water, swish for 30 seconds, and spit. Do this at least three times a day, but not much more than that. If your mouth is very tender, start with half a teaspoon of salt for the first day or two, then increase to the full amount.
Brushing twice daily with a soft-bristled toothbrush and flossing once a day are non-negotiable during a gum infection, even though it might be uncomfortable. Bacteria trapped along and below the gumline are driving the infection, and mechanical removal is the most effective thing you can do between dental visits. An antiseptic mouthwash can help as an add-on, but it’s not a substitute for brushing and flossing.
Professional Deep Cleaning
For most gum infections that have progressed beyond mild gingivitis, the standard first-line treatment is a procedure called scaling and root planing. The American Dental Association recommends it as the initial nonsurgical treatment for periodontitis, noting that it provides a moderate benefit and that the advantages outweigh potential side effects.
Here’s what happens: your dentist numbs your gums with a local anesthetic, then uses hand instruments or ultrasonic tools to remove plaque and tartar from your teeth, both above and below the gumline. After that, they smooth the surfaces of your tooth roots. This smoothing step matters because rough root surfaces give bacteria places to cling and recolonize. Once the roots are smooth, your gum tissue can reattach more easily.
The procedure is typically done in one or two visits, depending on how widespread the infection is. Ideally, you only need it once. After the bacteria and tartar are removed, regular dental cleanings and good daily hygiene should keep the infection from returning.
When Antibiotics Are Needed
Your dentist may prescribe antibiotics if the infection is more aggressive or hasn’t responded to cleaning alone. Treatment courses typically run 3 to 7 days, though more complicated infections may need longer. In some cases, antibiotics are injected directly around the tooth roots during a deep cleaning procedure rather than taken as pills.
The ADA’s clinical guidelines note that low-dose antibiotics used alongside deep cleaning show benefits with fewer side effects than full-strength courses. Local treatments placed directly at the infection site, like antibiotic chips or gels, are another option, though the evidence supporting them is less robust.
Medicated Mouthwash
Your dentist may prescribe a chlorhexidine mouthwash, which is a stronger antiseptic than anything available over the counter. It’s effective at killing the bacteria driving gum infections, but it’s designed for short-term use only, typically up to four weeks. Using it longer can stain your teeth brown. Follow the prescribed duration and switch back to a regular antiseptic rinse when the course is finished.
Recovery Timeline by Severity
Mild infections (gingivitis with some bleeding and swelling) can begin improving within a week when you combine professional cleaning with solid home care. You should notice less bleeding when you brush and reduced redness at the gumline.
Moderate infections that require deep cleaning and possibly antibiotics generally show noticeable improvement within two to three weeks. Your gums will still be healing during this period, and some sensitivity is normal.
Severe infections, particularly those involving significant bone loss or abscesses, may need surgical treatment. Recovery from gum surgery can take several weeks to months, depending on the procedure. Your dentist will schedule follow-up visits to monitor how the tissue is healing and whether the pockets between your gums and teeth are shrinking.
Why Treating a Gum Infection Matters Beyond Your Mouth
Chronic gum disease doesn’t stay in your mouth. People with periodontitis have elevated levels of inflammatory markers circulating throughout their bloodstream. The American Heart Association has published a scientific statement outlining several mechanisms that link periodontal disease to cardiovascular disease, including bacteria from infected gums entering the bloodstream and triggering inflammation in blood vessel walls. Gum disease is also associated with poorly controlled diabetes, with the relationship running in both directions: high blood sugar makes gum infections worse, and active gum infections make blood sugar harder to control.
Preventing Reinfection
Once you’ve cleared a gum infection, the goal is to keep bacteria from building up again. Brush for two minutes twice a day, floss daily, and keep up with dental cleanings on whatever schedule your dentist recommends. For people with a history of gum disease, that’s often every three to four months rather than the standard six.
Smoking is the single biggest modifiable risk factor for gum disease. It reduces blood flow to the gums, slows healing, and makes treatment less effective. If you smoke, quitting will do more for your long-term gum health than almost any other change. Other factors that increase your risk include uncontrolled diabetes, hormonal changes during pregnancy, and medications that cause dry mouth, since saliva is one of your body’s natural defenses against oral bacteria.
